Publication number: 20100244555Abstract: A three-phase generator includes an output voltage settable between a first voltage value and a second voltage value, in which the first voltage value is provided for supplying electrical system consumers of a motor vehicle. The second voltage value is greater than the first voltage value. The three-phase generator has a stator around whose teeth a three-phase winding is wound, whose winding phases are positioned in slots located between the teeth. To ensure a balanced power ratio within the different voltage levels, each winding has a predefined number of conductors per slot.Type: ApplicationFiled: July 14, 2005Publication date: September 30, 2010Inventors: Herbert Labitzke, Gert Wolf, Reinhard Meyer

Patent number: 7679219Abstract: Power supply devices for vehicle electrical systems in particular, including two voltage systems, i.e., vehicle electrical systems, each having its own generator. The first generator and the battery belong to the same voltage system, and the second generator belongs to the second voltage system. If the two voltage systems were decoupled, the second generator would not have the excitation current required for starting, so means are consequently provided here to connect the second generator to a charge storage device after actuation of the ignition switch, thereby generating an excitation current; this charge storage device may also be the battery of the first voltage system and the connection is kept conductive until the second generator starts and is generating an output voltage.Type: GrantFiled: February 9, 2005Date of Patent: March 16, 2010Assignee: Robert Bosch GmbHInventors: Herbert Labitzke, Andre Micko

Patent number: 7301309Abstract: A method and a device for providing the supply voltage for the loads of a vehicle on-board electrical system, using a plurality of generators. A regulator unit having at least one output stage transistor is allocated to each of the generators. The output stage transistor is controlled by means of a pulse-width-modulated control signal. The control signal generated in one of the regulator units, or a control signal derived therefrom that describes the pulse-duty factor of the pulse-width-modulated signal, is also supplied to the regulator units of the additional generators, and is also used there to control the output stage transistors. This procedure may bring into agreement the degree of loading of the generators.Type: GrantFiled: March 10, 2006Date of Patent: November 27, 2007Assignee: Robert Bosch GmbHInventors: Herbert Labitzke, Helmut Suelzle

Patent number: 6696914Abstract: The invention relates to an electrical fuse for rotary current generators, having a rectifier assembly (14) for supplying a DC network, in particular in motor vehicles. To achieve simple, cost-effective and rapid-response fuse performance in the event of an overload, it is provided that a fuse element (21) be disposed in a line strand, carrying all the generator current, between the rectifier assembly (14) and a DC connection terminal (22) of the generator.Type: GrantFiled: January 25, 2002Date of Patent: February 24, 2004Assignee: Robert Bosch GmbHInventors: Martin Haupt, Herbert Labitzke, Walter Csicser, Klaus-Uwe Mittelstaedt, Holger Scholzen, Karl-Otto Heinz, Holger Haussmann, Henning Stilke

Patent number: 6667532Abstract: The invention concerns a semiconductor power element (diode 18) having a lead (11) and a safety fuse (12) situated in the main current path that blows when overheated, particularly for use in the electrical system of motor vehicles. In order to achieve a previously determined, purposeful disconnection of the endangered element in order to avoid consequential damages when semiconductor power elements become overloaded, it is proposed that a segment (11b) of the lead (11) and/or its points of contact in the main current path of the semiconductor be designed as a safety fuse (12) that blows when a specified, current-dependent temperature value is reached.Type: GrantFiled: January 24, 2002Date of Patent: December 23, 2003Assignee: Robert Bosch GmbHInventors: Martin Haupt, Herbert Labitzke, Walter Csiscer, Klaus-Uwe Mittelstaedt, Hans-Heinrich Winkel, Holger Scholzen, Karl-Otto Heinz, Holger Haussmann, Henning Stilke, Hermann Lehnertz

Publication number: 20020167772Abstract: The invention concerns a bridge rectifier for rotary current generators, in particular for supplying the electrical system of motor vehicles. It comprises rectifier diodes and a printed circuit board comprising an insulator (23) basically designed in the shape of a plate, in which multiple connection conductors (24) are embedded between the diodes of the rectifier bridges, whereby sections of these connection conductors are designed to be bent extending out of the insulator and as fuses (25) that melt in case of electrical overload. In order to achieve the smallest possible tolerances for operation of the fuses, each of the fuses (25) is formed out of two conductor ends (24a)-bent to the outside-of the connection conductors (24) and a fuse element (29) connected with them that bridges the conductor ends.Type: ApplicationFiled: January 2, 2002Publication date: November 14, 2002Inventors: Martin Haupt, Herbert Labitzke, Walter Csicser, Klaus-Uwe Mittelstaedt, Holger Scholzen, Karl-Otto Heinz, Holger Haussmann, Henning Stilke, Hermann Lehnertz

Patent number: 5236056Abstract: A method for assisting the steering forces to be produced in a vehicle by means of an electric motor acting on the steering column is proposed. This method is characterized in that the additional torque produced by the electric motor is controlled in dependence upon the steering torque to be produced for actuating the steering and upon the steering torque supplied overall. The additional torque is thus dependent on the torque which is produced at the steering wheel by the driver and, in addition, on the torque which is supplied by the steering arrangement on the wheels to be steered. The electric motor is controlled by a controller 5 via an actuator 6, an additional torque M*.sub.R, which is dependent on the vehicle speed, being input into the controller. As characteristic shaper, the controller has a dead-time element by which the control intervenes only from a certain limit value of the torque M*.sub.R input into the controller 5.Type: GrantFiled: May 18, 1992Date of Patent: August 17, 1993Assignee: Robert Bosch GmbHInventors: Peter Pfeffer, Herbert Labitzke, Peter Ahner, Peter Kleindieck, Willibert Schleuter, Uwe Kirberg
